Overview
IEC 62453-309:2022 - "Field device tool (FDT) interface specification - Part 309: Communication profile integration – IEC 61784 CPF 9" provides guidance for integrating HART® (CPF 9) communication profiles into the FDT framework (IEC 62453-2). It defines the communication and supporting services required for FDT Device Type Managers (DTMs) and hosts to work with HART Basic and Extended HART protocols (based on IEC 61158-5-20 and IEC 61158-6-20). This part does not contain or modify the FDT specification itself; it describes how to map HART protocol behaviour, addressing and data types into the FDT model. Edition 3.0 (2022) is a technical revision that clarifies device data access and support for protocol versions.
Key Topics
- Protocol integration scope: Mapping HART CPF 9 into the FDT architecture; distinction between HART_Basic and Extended_HART.
- Bus category & physical layer mapping: Definitions for HART transport within FDT channels.
- Access to device and instance data: Process Channel objects provided by DTMs and DTM services for read/write access.
- Protocol-specific behaviour: Burst mode subscription, use of device addressing, extended command numbers, handling of failures, time-outs and delayed responses.
- Mixed-protocol topologies: Rules for DTMs when networks contain multiple HART protocol versions or nested gateways.
- WirelessHART considerations: Network topologies, gateway and adapter integration, and FDT topology models for WirelessHART.
- Data models and types: Protocol-specific definitions for communication data types, channel parameters, network management, device identification and scan identification (structured and simple forms).
- Interoperability & conformance: Guidance to ensure consistent behaviour across hosts, DTMs and gateways.
Applications
- Integrating HART field devices into FDT-compliant asset management systems and control systems.
- Implementing or updating DTMs to support HART Basic, Extended HART and WirelessHART.
- Designing FDT host applications that perform topology scans, device identification, burst subscriptions and robust error handling for HART networks.
- Supporting mixed wired and wireless HART deployments and multi-gateway architectures.
Who uses this standard
- Device manufacturers creating HART-enabled instruments and DTMs
- System integrators and control system vendors building FDT hosts or integrating HART devices
- Automation engineers responsible for device lifecycle and asset management
- Test, certification and interoperability labs validating FDT/HART implementations
